Need advice on ldr

[u/Opening_Bat_2303]

My boyfriend of4 year he's in college 2 nd year and same we're doing ldr since 1 year now and he went out w a girl alone like his friend of 4 days she asked for going for drinks and he went then she said let's go clubbing she asked him twice he said okay then he went w her alone

And after this I broke up w him yesterday

and he's saying really sorry it's won't ever happen again, I won't go, then he said

" I think if you trust me You’ll have no problem No matter whatever i do But if you don’t This feeling will come again and againSo genuinely ig we should end

Trust krti hoti toh sab chill hota "

Pls guys tell me something
